Be it known that I, F Rrrz FiNo-KH, re-

new and useful Improvement in Barrel- Recoil Guns, of which the following is a specification. y

This invention relates to barrel recoil guns and the object of the invention is to enable the gun barrels of naval and railway guns, which are to bemade, or already eX- istant naval guns to be used both on a naval carriage or a railwaycarriage without im- Y portant alterations `being made in the gun barrels and cradles.

The invention Win bn described with nefrkerence to the accompanying drawings in Which'- Figure 1 is a side elevation of a barrel recoil gun showing the parts pertaining to the present invention.

Fig. 2 is the corresponding left hand end view and .Y Y Y Y Fig. l3 the corresponding plan view.

Figs. 4 vto 6 are views corresponding to Figs. 1 to 3 of a second construction.

Figs. 7 to 9 aresimilar views of a further construction usual hitherto and Fig. 10 is a side elevation, partly in section, of the gun barrel of Figs. 7 to 9 but altered according to the invention.

Fig. 11 is a section on the line 11-11 of Fig. 10, looking from the left, and

Fig. 12 is the corresponding plan view to Fig. 10.

The arrangement shown in Figs. 1 to 3 will be described first.

The gun barrel A is carried by a cradle B, which cradle carries two pairs of trunnions (E, El) the geometrical axis of which trunnions E passes either through the center of gravity of the parts of the gun which are swung when the elevation is made or lies in the vicinity of this center of gravity, while the trunnions El lie very near the breech end of the gun barrel.

If the parts described are to be used for a naval gun, the trunnions E are laid inthe bearings provided on the gun carriage. If, on the other hand, the parts illustrated are to be used for a railway gun carriage, they are carried by means of the trunnions E? in the railway gun carriage frame. The parts which oscillate about the axis of the n trunnions are then considerably preponderant in weight at the front, which preponderance of weight has to be compensated by an equalizer, but no provision need beV made for the parts lying behind the trunnions, particularly the recoiling gun barrel, as for instance by preparing a pit between therails or by an arrangement for enabling the trunthe profile of the railwayloading gages to bev transferred from the transport position lnto'a higher firing position. Y

lheconstruction shown in Figs. t to 6 ldiffers only from that described, in that the .cradle F is providedwith an arrangement for enabling Va pair of trunnions (Gr) to be detachably fixed in either of two different positions of the cradle. For this purpose the .cradle has two pairs of oppositely lo-` cated fiat surfacesv (f1, f2) onwhich plates g1, which are in one piece with the ,trun-r nions G, are to be affixed by screws.' The plates g1 carry disk shaped members g2, in-

v Fig. ,in thebody of the cradlezand there- Vby take the pressure-oif from the attachment screws. If the parts'illustrated are toy mbeusedy on a naval gun carriage, thetrunnions G are attached to the front flat faces (f1) of the cradle, whereas when the parts are used on a railway gun carriage the trunnions are to be screwed to the rear flat faces (f2).

The cradle H shown in Figs. 7 to 12 carries a pair of trunnions J, which is mounted on one end of the cradle. The cradle H also carries a member h1, in which the cylinder K of a recoil brake and a running out gear is attached in an easily detachable manner. The corresponding piston rod k1 can be attached to a horn fm1-on ay ring M rigidly attached-to the gun barrel. On the member h1 an eye 71,2 is mounted for a purpose to be hereinafter described.

When the cradle H together with the gun barrel, brake, and the like is used for a naval gun, these parts are put together in the manner shown in Figs. 7 to 9. The trunnions J then lie at the end of the cradle which is next to the muzzle of the gun barrel, and the elevating gear is attached tothe eye k2. If on the other hand the arrangement shown in Figs. 7 to 9 is to be built into a railway gun carriage, the cradle H is inserted in the frame of thegun carriage in a reversed po sition (see Figs. l0 and l2). 1 y

The end of the Ycradle which carries the trunnions J 'is then located in the vicinity of the breach of the gun barrel. In this case the easily detachable cylinder K, which is` connected to the member h1 of the cradle I-I, must also be reversed, so that the end of the cylinder which is Aprovided qwith a 'stuling Y against vthecradle H when the gun is n thev firing position, or if the distance of the trunnions J from the .breach'lend of ther gun barrel is Vto be lincreased `and the preponderant weight in front vof the parts oscillating about the'trunnions is to be reduced, -a ring N may .be inserted between the rear endofthe cradle VH and the ring M and be attached to thev The ring-N islprovided with aprocradle. jjec'tlonfn1 whlchcarries an eye n2 for the attachment ,of .the elevating'gear and has-a :boring n?" for the rods 701.702. yThe last described arrangement is vspecially suited for theconversion of existing naval guns.

Y The :ring Nimay also be usedin thecon- `vstructionsshown in Figs. l to 6. In this case the piston'rodzof the'recoil brake ofthe running out'fgear `must naturally also be f =lengthened.

Claims. Y v v1. A barrel recoil gunV which comprises a gun barrel, a cradle, land means .on said cradle Vwhereby the horizontal axis about j which the .gun barrel oscillates can be Y When the cradle H -is used on aV .brought to distances of different length from the breech Vend ofthe cradle.

2. A barrel recoil gun which comprises a gun barrel, a cradle, means carried 'by'said cradle to Venablethe gun barrel to be supported on. horizontal axes at distances of different lengths from the, breech end of the gun barrel, a recoil brake and run-out gear carried byv said cradle and extensible means for vconnectingthe recoil device to the gun barrel.

3. Abarrel recoil gun which comprises a Vgun barrel, a cradle therefor, two pairs of trunnions carried by said cradle whereby the *horizontal axis about which the gun barrel oscillates may be brought to different -dis-V tances from the breechiend ofthe gun barrel..

4. A barrel recoil gun which comprises Aa gun barrel, a cradle therefor, trunnions carried'by said cradle,said trunnions being .arranged so that the horizontal axis about which the gunj barrel 1 oscillates may be y"brought v'Lto different distances from 'the .breech end of the cradle.

5. A barrel :recoil gun which comprises a gun barrel, a cradle therefor, two'pair of trunnions rigidly carried by said cradle, said pairs of -trunnions being spaced longitudinally on said cradle, whereby the horizontal `axis about :which the gun barrel oscillates may be brought 'to different `distances from the breech end of thevgun barrel.
